    keyword=Swing shift summary

    16:00 Starting the shift in DVCS production: P0=2.591GeV/c, theta=21.49deg.
    16:09 No beam due to accelerator IOC problem
    16:10 Gas shed airflow alarm went off for about 10 seconds
    16:48 Beam back. Resumed production data taking.
    17:00 No beam. MCC has BPM problem.
    17:45 Beam back. Resumed production data taking.
    19:27 Change of plan. Calorimeter off for LHRS delta scan/overlap test
    19:38 LHRS is ready at P0=2.643GeV/c (Q2 and Q3 have been cycled)
    21:30 LHRS is ready at P0=2.591GeV/c
    22:57 LHRS is ready at P0=2.539GeV/c
    23:47 MCC informed us that one of our dipole tripped off. We will be down for a little bit.
    23:53 Beam back, resume Al dummy run.
    00:00 Moving target to LH2 for last run of delta scan.
